Built from alloy steel with a black oxide finish, it meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical and structural assemblies. The 1\/4-20 UNC thread is fully threaded along the 1-1\/8 inch length under head, driven with a 3\/16 inch hex key. Machinists, millwrights, and general maintenance tradespeople install this fastener in equipment, fixtures, and fabricated assemblies where a flush or recessed head is required.\u003c\/p\u003e\u003cp\u003eThis screw is used across a wide range of industrial and commercial applications including machinery guarding, equipment enclosures, tooling fixtures, and mechanical assemblies. The 1\/4-20 UNC thread standard is one of the most common inch-series thread sizes, making this fastener appropriate for general-purpose bolted connections in light to medium mechanical assemblies. Its black oxide finish provides a degree of corrosion resistance suitable for indoor and protected environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eFully threaded 1-1\/8 inch length under head for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003e3\/16 inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread form conforms to ASME\/ANSI B18.3\u003c\/li\u003e\n\u003cli\u003eSold individually with a minimum order quantity of 100 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and general-purpose replacement or stock fastener for any assembly requiring a 1\/4-20 UNC hex socket cap screw with a 1-1\/8 inch length under head per ASME\/ANSI B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 3\/16 inch hex key or appropriately sized Allen driver. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards for 1\/4-20 alloy steel fasteners. Do not exceed the rated torque for the fastener grade, as over-torquing can cause thread stripping or fastener failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Socket Cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 581369P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718306496818,"sku":"581369P","price":6136.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b707897ee6c02dfab11c426f6c22cd7d.jpg?v=1788551857","url":"https:\/\/voomisupply.com\/products\/value-collection-581369p-1-4-20-unc-socket-cap-screw-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
